To use 3-dimensionsal antennas, including beamforming and MIMO antennas, with EDX software, the data describing the 3-dimensional patterns must be stored in a file, same as in the 2-dimensional case. This is an ASCII data file you can prepare yourself to use using a text editor or using the 2-dimensional antenna pattern file creation utility function (see Create/Edit a 2-Dimensional Antenna Pattern File). This file is a tabulation of azimuths and relative field or dB values that describe a single section or slice of a 3-dimensional antenna pattern. Both horizontal and vertical plane pattern values can be listed in the file.

To begin building a section or slice of the 3-dimensional pattern:
Open a spreadsheet in excel or sheets.
Place the header in the first row. This will be the antenna name in single quotations, the maximum gain of the antenna, and the value signifying whether the following tabulated pattern data is in relative field strength or relative dB.
Next, list in two columns all the horizontal azimuths and their associated gains, either 0 to 360 degrees, or -180 to 180, with a maximum increment between azimuths of 45 degrees.
The next entry will be the code “999”.
Below that enter how many slices you have and the number of points or values within each slice.
Next, enter in the 0-degree azimuth
On the next line begin to list out the vertical slice. List all vertical azimuths and gains in each slice from -90 to 90.
If only utilizing one slice, your pattern is complete. If you have 2 or more slices, you will need to list the value in degrees that each slice is based on. The more data you can include (ie; the more azimuths and gains) the more accurate your pattern should display and give results.
